Abstract

Se describen técnicas para transmitir datos de piloto y de tráfico. En un aspecto, una terminal puede encriptar su piloto con una secuencia de encriptación generada con base en un conjunto de parámetros estáticos y dinámicos. El(los) parámetro(s) estático(s) tiene(n) valor(es) fijo(s) para toda una sesión de comunicaciones para la terminal. El(los) parámetro(s) dinámico(s) tiene(n) valor(es) variable(s) durante la sesión de comunicaciones. La terminal puede generar una secuencia de encriptación al dispersar el conjunto de parámetros para obtener una semilla e inicializar un generador de PN con la semilla. Después, la terminal puede generar la piloto con base en la secuencia de encriptación. En otro aspecto, la terminal puede utilizar diferentes secuencias de encriptación para los datos de piloto y de tráfico. Una primera secuencia de encriptación puede generarse con base en un primer conjunto de parámetros y utilizarse para generar la piloto. Una segunda secuencia de encriptación puede generarse con base en un segundo conjunto de parámetros y utilizarse para encriptar los datos de tráfico.
